Avoid if you take the Purple Ljne – Transit Stop: CTA Tracker. Review

This app may work for certain train and bus lines, but if you take the Purple Line do NOT download it. The purple line is unpredictable enough as it is, and this app does a terrible job of giving you accurate information. Estimated train arrival times will move significantly in either direction and, worst of all, it will often times just give you the completely wrong information. For example, times that are listed as Brown Line trains are actually times listed for Purple Line trains, and vice versa. You’re better off just leaving at a set time each day than using this app.
